Broadcom HCPL-0501-000E High-Speed 1-Channel Optocoupler, SOIC-8
Broadcom 1-channel optocoupler with 3.75kV isolation & 1Mbps speed for TTL circuits. Ideal for noise suppression & signal isolation.
The Broadcom HCPL-0501-000E is a high-speed, 1-channel optocoupler designed for reliable signal isolation in demanding digital circuits. It utilises a sophisticated diode-transistor configuration with an insulating layer between the input LED and an integrated photo-detector, providing robust electrical insulation between input and output sides.
A key feature is the separate connections for the photodiode bias and the output-transistor collector. This innovative design significantly reduces the base-collector capacitance, resulting in a speed increase of up to one hundred times compared to conventional phototransistor couplers. This makes it perfectly suited for high-speed TTL and TTL-level applications.
Performance and Compatibility
The device is designed for seamless integration. A standard 16mA TTL sink current through the input LED generates sufficient output current to drive one TTL load when used with a 5.6kΩ pull-up resistor. It offers a high-speed data rate of 1Mbps and features an open-collector output for flexible interfacing. Performance is guaranteed across a broad operating temperature range of 0 to 70°C, ensuring stability in various environmental conditions.
Reliable Insulation
With a high isolation voltage of 3.75kV, this optocoupler provides excellent protection against voltage transients and ensures safe separation between different circuit domains. It is an essential component for enhancing system safety and noise immunity in power supplies, motor controls, and communication interfaces.
Handling Note
As with all sensitive semiconductor devices, it is advised that normal static precautions (ESD handling) be taken during the handling and assembly of this component to prevent potential damage or performance degradation.
